The objective was to compare insulin resistance parameters in cows with adequate or excessive energy intake as well as in cows with excessive energy intake receiving Cr supplementation as chromium propionate. Thirteen multiparous, nonlactating Gir × Holstein cows were ranked by BW and BCS and assigned to 1 of 3 dietary treatments on d 0: 1) diet to meet their ME requirements without Cr suppleme...

An enzyme preparation from Cryptococcus laurentii catalyzes the transfer of glycosyl units from sugar nucleotides to exogenous acceptor resulting in the stepwise synthesis of a heteroglycan with the following structure: Z-O-a-n-mannosyl6-O-oc-D-mannosyl-3-~-~-D-mannosyl-(2 -0 -0 -D -xylosyl-) D-mannose. The same enzyme preparation transfers D-[‘T]mannosyl from GDP [WJmannose to an endogenous gl...

We use the Malkin theorem to derive phase equations for networks of weakly connected relaxation oscillators. We find an explicit formula for the connection functions when the oscillators have one-dimensional slow variables. The functions are discontinuous in the relaxation limit μ → 0, which provides a simple alternative illustration to the major conclusion of the fast threshold modulation (FTM...

A number of radically distinct models (inquiry systems) are described. The models derive from C. West Churchman’s recent characterization of the history of Western epistemology. It is argued that only a few of these models are appropriate for technological forecasting problems. Most technological forecasting methodologies rest on a dubious philosophical foundation. They unreflectively assume th...

Background: The herbicide 2, 4-dichlorophenoxyacetic acid (2, 4-D) can cause moderate to lethal poisoning. Although urine alkalization has been recommended as the main treatment, hemodialysis (HD) may be more effective in severe cases. Case: On 24th June 2014, a 53- year-old man ingested a high amount of 40% 2, 4-D. He suffered from mouth and epigastric burning sensation, vomiting and nausea...
